For the 6th year, Chicago has been named the rattiest city. The pest control company Orkin compiles the list each year.
The ranking is based on the number of new rat treatments they provide from September to August of each year.
Los Angeles, New York City, Washington D.C. and San Franciso rounded out the top 5.
West Palm Beach in Florida is No. 50 on the list.
The best news is that Las Vegas did not make the top 50 list of cities despite recent reports of an increase in rat activity in the city.
